Ranier Anatom-C – Spinal Disc Replacement

The Ranier Anatom-C was designed to treat patients with degenerative intervertebral discs. The design satisfies both the needs of the patient and surgeon along with stringent high tech manufacturing requirements.

The device is an anterior cervical inter-body fusion cage and is implanted between the vertebrae of the cervical spine to provide mechanical stability and space for fusion to occur.

The design requirements were established through surgeon input which allowed a complex and fully parametric base 3D CAD model to be built using the advanced surfacing capabilities of PTC Creo.

To ensure optimum fit with the patient’s anatomy a single CAD model was created from which a range of sizes were parametrically generated. This model controlled all size variants to ensure that the design parameters were scaled in accordance with the anatomical needs and met the manufacturing requirement.

The design was optimised through collaboration with an FEA analysis consultant prior to manufacture and rigorously tested to achieve CE approval.
